Auto-reboots a frozen router so your internet fixes itself. No cloud, no subscription.

The PumpFuse Internet Watchdog watches your connection around the clock and automatically power-cycles your router when it stops responding — then verifies the internet is actually back before resuming. Perfect for vacation rentals, remote setups, and anyone tired of manual reboots.

What it does

Auto-fixes frozen internet — no more manual reboots. Continuously monitors your connection by pinging 3 independent DNS servers every 60 seconds. All must fail multiple consecutive checks before action is taken to help prevent false alarms. When your router becomes unresponsive, it automatically power-cycles it and verifies the connection is restored before resuming monitoring. Operates 24/7 while you sleep, travel, or work.
Smart retry logic — prevents rapid reboot cycles. Built-in grace periods allow your internet time to recover before any reboot. If the first restart doesn't resolve the issue, it waits 30 minutes and retries, up to 3 total attempts. If the problem persists, it stops retrying and provides LED and app indication — avoiding unnecessary reboot loops.
Scheduled daily reboots — optional preventative maintenance. Set a daily reboot time, such as 4:00 AM, to refresh your router and help reduce slowdowns. Ideal for vacation rentals and short-term rentals that require consistent guest Wi-Fi. Uses the same controlled reboot process with connection verification.
Free PumpFuse app — setup in about 60 seconds, no account required. Download the app for iOS or Android, connect via Bluetooth, enter your Wi-Fi credentials, and finish in minutes. Monitor status, review event history, adjust settings, and trigger manual reboots from your phone. No cloud account, no subscription, no ongoing fees.
Smart home and developer ready. Automatically discovered by Home Assistant via MQTT with 11 entities including sensors, switches, and controls. Includes a full local REST API accessible via a device-specific .local hostname, and a built-in MCP server for OpenClaw and other compatible AI assistants. Designed for local network control.

Frequently asked questions

Does it need a cloud account or subscription?

No. Setup takes about 60 seconds with the free PumpFuse app (no account), and the device then runs entirely on your local network — no cloud, no monthly fees.

Will it reboot my router constantly?

No. It only acts after multiple consecutive failed checks, uses grace periods, and retries at most 3 times (30 minutes apart) before stopping and signaling via LED and app.

Can I integrate it with Home Assistant?

Yes. It's auto-discovered over MQTT with 11 entities, and also offers a local REST API and an MCP server for AI assistants.

Is this the same hardware as the Pond Pump Protector?

It uses the same compact PFA01 hardware, but the firmware and purpose are different. The Pond Pump Protector works with no app; the Internet Watchdog uses the app for setup.
